Parliamentary vs Presidential: Bangladesh vs Senegal

How their governments are structured

Bangladesh is a parliamentary republic; Senegal is a presidential system. The second split is how the executive is chosen. Bangladesh runs a parliamentary system: the head of government (a prime minister or chancellor) holds office only as long as they keep the confidence of the lower house, and a successful no-confidence vote forces resignation or new elections. Senegal runs a presidential system: the head of state and head of government are the same elected office, with a fixed term that the legislature cannot end through ordinary votes. The practical effect is that the presidential side has fixed terms and an executive that cannot be removed by the legislature short of impeachment, while the parliamentary side can replace the head of government mid-term through a confidence vote.
